Add certFile and certKeyFile to SoapStubAdapter

SoapStubAdapter uses the schemeArgs dictionary to pass HTTPConnection and HTTPSConnection parameters around.
However, with the planned Python 3.12 changes, some parameters will no longer be supported.
This changes adds certFile and certKeyFile as SoapStubAdapter class attributes and updates the current consumers.
